The inventory turnover ratio for Coherent Inc. over the periods provided reflects fluctuations in the efficiency of inventory management. As of September 30, 2022, the inventory turnover stood at 2.27, indicating that the company sold and replenished its inventory approximately 2.27 times during that fiscal year. By June 30, 2023, this ratio increased to 2.78, suggesting an improvement in inventory utilization and more frequent sales cycles. This elevated ratio persisted through September 30, 2023, at 2.78, indicating stability in inventory turnover during that period.

However, a subsequent decline is observed by June 30, 2024, where the ratio decreased to 2.53. This reduction signals a slight slowing in the frequency of inventory turnover, potentially implying a buildup of unsold stock or reduced sales velocity. The most notable change is seen in the data for June 30, 2025, where the ratio sharply drops to 0.04. This drastic decline indicates that the company was turning over its inventory extremely slowly, potentially due to substantial inventory accumulation, write-downs, or other operational challenges leading to inefficient inventory management.

Overall, the trend demonstrates an initial improvement followed by a significant deterioration in inventory turnover efficiency, culminating in a potentially concerning level of inventory holding relative to sales activity by mid-2025. This pattern warrants further examination into operational practices, sales performance, and inventory management strategies during these periods to understand underlying causes and implications.
